Question

5. The alkyl group of Grignard reagent act as:
(A) Free radical (B) Carbonium ion
c) Carbonion (D) None of above​

Answer 1

d) none of above

Step-by-step explanation:

Grignard Reagents. The Grignard Reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form a tertiary or secondary alcohol, respectively. The reaction with formaldehyde leads to a primary alcohol.

Answer 2

The alkyl group of Grignard reagent act as Carbanion

Explanation

Organomagnesium halides, also known as Grignard reagents, are produced when magnesium metal reacts with haloalkanes and other compounds containing the halogen atom attached to either sp3-hybridized or sp2-hybridized carbon atoms (aryl and vinyl halides).

Diethyl ether (CH3CH2OCH2CH3) is typically used to make Grignard reagents. For the reaction to occur, an ether solvent is required.

Acidic hydrogen atoms in compounds like alcohols and water react quickly with Grignard reagents. An alkane results from the reaction of a Grignard reagent with water when a proton takes the place of the halogen. In order to convert a haloalkane to an alkane in two stages, the Grignard reagent is available.

R - X → R- Mg - X

R(-) is the Carbanion

Hence the carbanion is the correct answer
